The salt needs of all individuals are highly variable since they depend on different factors such as climate (hot weather is needed to eat more salt than cold weather), work (those activities that require more effort and increase the required sweat intakes of salt), etc.
To avoid excessive intake of salt the World Health Organization recommends that salt intake is between 500 mg daily minimum and maximum 2000 mg daily. We must be extremely careful with those foods high in salt to avoid eating more salt than necessary.
Most of the excess salt is produced by adding this in the food when cooking or eating packaged food or prepared with salt, preservatives or flavoring made based on salts. These would include preservatives such as sodium nitrate or flavorings such as monosodium glutamate.
When should we eat salt?
One should not salt fish or meat. A diet rich in fruits and vegetables helps to contain salt intake.
